Manchester United is not as bad as you think they are now. They've made quite some changes on their defense team. One young player name Haven made their defense more stronger than it use to be. Also, some attackers has step up their game while defending. Players like Holjund, Garnacho, still with their captain Fernadez. Anyway what i am trying to say here is the fact that there are odds you can still bet on Manchester United to win. Only avoid teams you feel Manchester United cannot win.
Their defence still doesn't stand solid even with the changes they have made, by the way the changes aren't even impressive, they are more like a rotational change and not an actual change to get the team the kind of result expected of them. The attacker are the only ones with actual visible and impressive changes that will be considered change enough. All of this sp gat haven't actually positioned Manchester United in a place where we can actually consider them solid now, they are still very much trying to keeping up with building some strength in areas where needed which actually feels like a holistically improvement actually.
